Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

vs2010 DotNet 4?
by Mark Tigges 03 Feb '12

03 Feb '12

The first thing one seems to have to do is define UCS4 Upon trying out building the PythonDotNet source tree with 2010 and dotnet 4 with UCS4 I get a bunch of errors related to the use of a namespace Mono. I tried excluding the monosupport.cs file, but the runtime.cs file seems to require it as well. It makes use of the Utf32Marshaler defined in monosupport.cs. Has no analogous work been done for Microsoft dotnet 4? Thanks, Mark.
